Personality Traits of Children With Vocal Fold Nodules

Play-Based Strategies for Speech Therapy and Vocal Health Face-to-Face and Distance Learning Actions for Children: An Integrative Literature Review

INTRODUCTION

Diversifying voice therapy strategies is critical to get children and adolescents to adhere to the therapeutic process.

PURPOSE

To investigate the face-to-face and distance playful strategies have been used for vocal health education and voice therapy in children and adolescents.

METHODS

An integrative literature review was carried out based on the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA). A search for full texts was conducted on the Virtual Health Library, Scientific Electronic Library Online (SCIELO) and PuBMed databases using the following descriptors, and their corresponding Medical Subject Headings (MeSH): voice (voz); voice quality (qualidade da voz); dysphonia (disfonia); voice disorders (distúrbios da fala); voice training (treinamento da voz); telemedicine (telemedicina); therapeutics (terapêutica); health promotion (promoção da saúde); group practice (prática de grupo); recreation therapy (terapia recreacional); child (criança); preschool (pré-escolar) and adolescent (adolescente).

RESULTS

After full reading of the studies, 15 articles were included and categorized into the following topics: face-to-face and distance playful strategies for voice therapy in children; playful strategies with gamification for education and for voice therapy in children; and vocal health educational actions in children.

CONCLUSION

The study found a higher number of studies that carried out educational actions and playful strategies, while fewer studies were related to the production of materials, gamification and online services for voice therapy in children. Given the proven benefits of this strategy for children, further studies focusing on the development and application of playful strategies, such as the use of gamification, should be conducted in order to stimulate the skills and adherence of this population to therapy.

Development and Validation of the Children's Voice Questionnaire (CVQ)

OBJECTIVES

This study developed and validated the children's voice questionnaire (CVQ), a new self-administered instrument for children, and evaluated its internal consistency and reliability.

STUDY DESIGN

Observational, prospective, cross-sectional study.

METHODS

The initial preparation of the CVQ was conducted in four steps. First, individual interviews were conducted with dysphonic and non-dysphonic children and their parents, teachers, and speech pathologists. Second, the responses collected from the interviews were arranged into a comprehensive list of 175 items. Third, this list was reduced to a preliminary 21-item version of the questionnaire, which was tested as a pilot with 254 children. Fourth, a further reduction to 18 items was performed to construct the final version of the CVQ. The questionnaire was then administered to 342 children (73 dysphonic, 269 non-dysphonic) aged 6-18. Simultaneously, the parents of these children completed the pediatric voice handicap index (pVHI). Finally, after 2 weeks, 30 randomly selected children (nine dysphonic, 21 non-dysphonic) completed the CVQ again to evaluate test-retest reliability.

RESULTS

High reliability was found for the CVQ (Cronbach's α = 0.94). Test-retest revealed strong and statistically significant reliability (r = 0.79, P < 0.001). A highly significant group difference was found between the CVQ scores obtained for the dysphonic and non-dysphonic groups (t[78.25] = 6.22, P < 0.001). In addition, significant medium-to-strong positive correlations were found between the children's evaluations using the CVQ and their parents' evaluations using the pVHI (0.59 < r < 0.66, P < 0.01).

CONCLUSIONS

The newly developed CVQ is a valid and reliable instrument. Findings reveal general agreement between children and their parents, but also show that children's perspective on their dysphonia is not equivalent to the parent's perspective. This demonstrates that combining both perspectives provides a more holistic and complete overview of dysphonic children's voice-related quality of life. The self-administered CVQ reliably differentiates dysphonic from non-dysphonic children and may serve as a valuable tool for the initial or ongoing evaluation of children with voice disorders in clinical and research settings.

Emotional Adjustment in Children with Vocal Fold Nodules

INTRODUCTION

Vocal fold nodules (VNs) in children are benign, bilateral, callous-like lesions at the junction of the anterior third and posterior two-thirds of the true vocal folds. Chronic, repetitive, and intense vocal behavior is often cited as the primary etiology; however, difficulties with emotional adjustment may predispose some children towards extreme and possibly phonotraumatic vocal activity, thereby contributing secondarily to the development of VNs.

OBJECTIVES

This case-control study examined the association between features of emotional adjustment and VNs in children.

METHODS

Parents of children with VNs (N = 40, Mage = 7.5, SDage = 2.03) and two medical control groups [ie, voice disordered, but not VNs (VDCs; N = 40, Mage= 7.09, SDage = 2.01) and vocally normal controls (VNCs; N = 40, Mage = 7.6, SDage = 1.54)] participated in the study. Features of emotional adjustment were assessed using two inventories: the Parent Rating scale for Reactive and Proactive Aggression and the Revised Child Anxiety and Depression Scale - Parent version.

RESULTS

As compared with the VNCs, children with VNs were significantly more aggressive (P = 0.042, Cohen's d = 0.47) whereas the VDCs were more depressed (P = 0.013, Cohen's d = 0.60). Furthermore, VDCs experienced more separation anxiety than VNs (P = 0.038, Cohen's d = 0.45) and VNCs (P = 0.021, Cohen's d = 0.55). No other significant between-group differences were identified between the VNs and VDCs.

CONCLUSIONS

When present, elevated aggression may represent a risk factor for VNs formation in children, and possibly influence treatment outcomes. Therefore, the current results highlight the importance of understanding the role of emotional adjustment in the evaluation and treatment of dysphonia in children.

Effects of voice therapy in children with vocal fold nodules: A systematic review

BACKGROUND

Vocal fold nodules (VFNs) are the main cause of paediatric dysphonia. Voice therapy is recommended as the preferable treatment option for VFNs in children.

AIM

The aim of this systematic review is to provide an overview of the existing literature concerning the effects of voice therapy in children with VFNs.

METHODS & PROCEDURES

This systematic literature review was developed following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (via PubMed) and Embase were searched and the grey literature was checked. The search strategy was based on three concepts: VFNs, voice therapy and children. Two examiners independently determined article eligibility and extracted all relevant data from the included studies. The methodological quality of the included study was assessed using the QualSyst tool.

MAIN CONTRIBUTIONS

By identifying, evaluating and summarizing the results of all relevant studies about voice therapy in paediatric VFNs, this systematic review makes the available evidence more accessible to voice therapists, otolaryngologists and other relevant stakeholders.

CONCLUSIONS & IMPLICATIONS

24 studies were included in this systematic review. Eight studies (8/24) reported a significant improvement for at least one outcome parameter after voice therapy. However, five papers (5/24) could not demonstrate significant changes after voice therapy. All studies that did not test for significance (11/24) found improvements for one or more outcome parameters. The overall quality of the included studies is adequate (55%). In sum, there is some evidence that voice therapy is effective in children with VFNs, but further well-designed research, especially randomized controlled trials, is necessary to confirm these results.

WHAT THIS PAPER ADDS

What is already known on the subject Voice therapy is preferable in children with VFNs because of the phonotraumatic nature of the nodules and the associated high recurrence rate after phonosurgery. Most voice therapists in clinical practice offer an eclectic voice therapy programme, consisting of direct and indirect voice therapy techniques. What this study adds to existing knowledge This systematic review provides a clear overview of the available evidence concerning the effects of voice therapy in paediatric VFNs. There is some evidence that voice therapy is an effective treatment option in children with VFNs, but well-designed research is scarce on this subject. What are the potential or actual clinical implications of this work? This review shows that effectiveness studies with strong designs are very scarce in children with VFNs. Clinicians should be aware that few therapy techniques have been thoroughly investigated in this population. However, this review may guide voice therapists when creating a treatment plan for a child with VFNs because it identifies, evaluates and summarizes the results of all relevant individual studies about voice therapy in paediatric VFNs. Voice therapy seems to be effective in treating paediatric patients with VFNs, given the fact that a considerable number of included studies report significant improvements after voice therapy. Both direct and indirect therapy approaches appear to have a positive effect on the phonation of children with VFNs.

Voice and Behavior of Children and Adolescents With Obesity: Integrative Literature Review

PURPOSE

To verify the relationship between obesity, voice and behavior in childhood and adolescence, through an integrative review.

METHODS

The researchers surveyed the articles indexed in the following databases: Embase, Web of Science, Scopus and Pubmed, using uniterms found in the Medical Subject Headings, related to the subject of the study, combined by the Boolean operators "and" and "or", published until January 2022. In the end, three reviewers selected the articles.

RESULTS

When searching for studies related to voice, obesity and behavior, 62 articles were found that did not meet the selection criteria and were excluded. Given this result, new searches were carried out with the following crossing strategies: voice and obesity and; Voice, Behavior and Child Behavior Checklist (CBCL). After the evaluation of the reviewers, two articles were selected referring to the intersection "voice and obesity in children and adolescents" and, two studies, in the intersection between "voice, behavior and CBCL". The first study on voice and obesity showed that the greater the abdominal circumference, the greater the maximum expiratory force and sound pressure found. The second study showed high Jitter and NHR values in obese children. Furthermore, studies on voice, behavior and CBCL showed that children with vocal nodules were more sociable than children without vocal nodules, and had behaviors described as "screams a lot" and "teases a lot". On the other hand, another study found potential risks of behavioral changes in the face of vocal complaints.

CONCLUSIONS

Although this literature review did not find studies associating obesity with vocal and behavioral disorders, the literature found showed the presence of vocal alteration in some acoustic parameters in obese children. Regarding voice, behavior and CBCL, two studies were found reporting the presence of behavioral changes in children with voice-related complaints, according to the opinion of their parents.

Personality in Children With Vocal Fold Nodules: A Multitrait Analysis

Purpose Vocal fold nodules (VNs) are bilateral, symmetrical, callous-like lesions secondary to phonotrauma and possibly related to specific personality traits. This case-control study examined the relation between personality and VNs in children within the context of the Trait Theory of VNs. Method Parents of children with VNs (N = 39, M = 7.43, SD = 2.01 years) and two medical control groups (i.e., voice disordered controls, but not VNs [VDCs; N = 40, M = 7.09, SD = 2.01 years] and vocally normal controls [VNCs; N = 40, M = 7.6, SD = 1.54 years]) completed the Inventory of Child Individual Differences, a personality instrument that describes the Big Five superfactors as well as 15 lower order personality traits. Results Children with VNs, as compared with VNCs, were (a) emotionally reactive (i.e., higher N-Neuroticism, p < .005, Cohen's d = 0.53), (b) Antagonistic, Strong-Willed, and less Compliant (i.e., lower A-Agreeableness, p < .014, Cohen's d = 0.59), and (c) Distractible and Disorganized (i.e., lower C-Conscientiousness, p < .009, Cohen's d = 0.62). Both voice disordered groups displayed elevated scores on the personality superfactor of Neuroticism (N; and the "Negative Emotions" lower order trait). Conclusions The combination of personality traits identified in this study (i.e., high N, low A and C) may play a central role in VNs development and possibly attenuate voice therapy success. Children with VNs displayed a similar personality typology as women with VNs, with the exception of elevated Extraversion (E), thereby providing support for the relevance of the Trait Theory of VNs in both children and adults. Clinicians treating children with voice disorders, including VNs, should consider their underlying personality traits in assessment and management.

Associations of Speaking-Voice Parameters With Personality and Behavior in School-Aged Children

OBJECTIVES

Previous studies suggest a link between voice disorders and personality traits. However, nearly nothing is known about the relationship between personality and voice parameters in healthy children. The present study investigated associations between children's personality and the intensity and frequency of their speaking voice.

STUDY DESIGN

This is a cross-sectional analysis.

METHODS

The study participants included 871 German children aged from 7 to 14 who had not yet experienced voice change in puberty. Within the framework of the LIFE Child study, all participants were asked to perform a speaking-voice task at four different intensity levels (quietest, conversational, presentation, and shouting voice). Associations of fundamental frequency and voice intensity with children's personality and behavioral strengths and difficulties (assessed using parent-reported questionnaires) were estimated using multiple linear regression analyses.

RESULTS

With respect to children's personality, the analyses revealed significant positive associations between speaking-voice intensity and extraversion (eg, for the conversational voice, β = 0.16, P < 0.001) as well as significant negative associations between voice intensity and emotional stability (eg, for the shouting voice, β = -0.15, P = 0.004) and conscientiousness (for the shouting voice, β = -0.10, P = 0.033). Regarding behavioral strengths and difficulties, we observed significant positive associations between voice intensity and peer-relationship problems (eg, for the conversational voice, β = 0.14, P = 0.001) and prosocial behavior (for the conversational voice, β = 0.11, P = 0.015). In contrast, no significant association was found between speaking fundamental frequency and personality or behavioral difficulties/strengths.

CONCLUSIONS

In children, associations exist between a child's speaking-voice intensity and his or her personality, especially extraversion and emotional stability, and behavioral characteristics.
